FLOAT-VALVE FOR TANKS.

Specification of Letters Patent.

Patented Oct. 22, 1912.

Application filed March 18, 1909. Serial No. 484,317.

To all whom it may concern:

Be it known that I, LOUIS A. CORNELIUS,

a citizen of the United States, residing at Grand Rapids, in the countyof Kent and State of Michigan, have invented new and useful Improvementsin Float- Valves for Tanks, of which the following is a specification.

In closet tanks, or other tanks, which it is desired should be emptiedby a valve which will open and automatically remain open until the tankis empty, it is customary to accomplish this purpose by using a bulb ofrubber, or other material buoyant enough so that it will float upon thewater normally, but of such construction that the suction effect willseat it and hold it seated until some force is exerted to remove it fromthe seat, whereupon it will rise to the top of the water, or as far asmechanical limitations permit, and remain buoyant in the water until itis again seated by what is spoken of as the suction effect. The properassembling of this valve float and its related parts in connection withthe other parts of the mechanism, and the proper adjustment of the same,present difliculties which it is the especial object of this inven-'tion to minimize; although the construction may be used in connectionwith valves of other types. Such a valve is lifted by a rod acting as avalve stem, and some suitable guide for suchvalve stem should beadjusted directly over the point of seating, since, if the valve doesnot rise and fall vertically, it will not seat properly. Different meansof thus properly adjusting and holding the valve stem have been used,but I find the means here shown to be particularly economical andefiicient.

In the accompanying drawings, Figure 1 is a side view of my devicecompletely assembled. Fig. 2 is a side view of part-s somewhat enlarged;and Fig. 8 is a vertical longitudinal section of the parts shown in Fig.2.

In these drawings 1 is the valve casting or seat of usual construction.I

2 is the overflow or waste pipe communicating with the escape pipe inthe usual way.

3 is any customary or suitable form of bulb or float valve having avalve stem 4 which slides in and is guided by the sleeve or guide 5. Thevalve stem 4: is lifted by mechanism of the usual construction which isnot a part of this invention and which I have not shown.

6 is a sleeve surrounding the overflow pipe 2 and adjustable thereonvertically and in the plane of a horizontal circle. It is clamped at anydesired point by suitable means, as by the set screw 7. This sleeve isextended on one side into a hollow projection 8, exteriorly threaded anddivided into longitudinal tongues by one or more slots 12.

The sleeve 5 is provided with an extension or stem 10 adapted to snuglyfit between the tongues and to be clamped by the tongues by turning thenut 13, slightly tapered'upon its interior and threaded on the extension8.

To adjust the parts to the position of the valve seat, the sleeve 6 isproperly positioned vertically and turned on the pipe 2 and then clampedby the screw 7 and the stem 10 is slid into proper position between thetongues and clamped therein by turning the nut 13.

I claim:

1. The combination of the valve seat, the valve, a stem therefor, asleeve for such stem, means for supporting such sleeve in connectionwith the valve seat, a stem projecting from such sleeve, a hollowchamber in connection with the supporting means, slots in the walls ofsuch hollow chamber and a nut having a taper thread,whereby the stem maybe adjusted in such hollow chamber and clamped in any desired adjustment2. In a device of the character described, the combination of a valvehaving a stem, a valve seat for the valve, a bearin -member for thevalve stem, and means for adjustably holding the bearing-memberrelatively to the valve seat comprising asupporting member havingtongues adapted to adjustabl'y hold the bearing-member between them, anda nut taperingly screw-threaded on the tongues and adapted when turnedto its operative position to clamp the tongues on the bearing member.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

LOUIS A. CORNELIUS.
